Methods and systems for blockchain and smart contract-supported decentralized computation are provided. A computation task from a task initiator node is registered on a blockchain by invoking a smart contract, and assigned to an edge computing node within a decentralized computing network, with task details sent by the task initiator node to the edge computing node through a secure peer-to-peer connection. The task initiator node and the edge computing node may select each other using peer discovery methods based on reputation scores. The edge computing node determines a solution to the computation task. The solution may be verified on-chain by the smart contract, or off-chain by the task initiator node, and a token reward may be given to the edge computing node by the smart contract upon solution verification. The edge computing node is incentivized to determine the solution by the reward provided by the smart contract.
